Spinal Cord Injuries - Coggle Diagram

- - - - Damage to centre with periphery unaffected (MC incomplete injury)
    - - Hyperextension or arthritic changes to c-spine
    - - Upper Limbs
        
        Motot and sensory abilities affected, mm weakness, flaccidity
      - Lower limbs
        
        Less affected
      - Bowel and bladder control normal or partially affected
  - - - Damage to anterior spinal artery/anterior SC
        
        Hyperflexion injury
    - - Bilateral loss of motor function, perception (pain, temperature, crude touch)
  - - - Damage to one side of SC. Caused by trauma i.e. gunshot/stab wound
    - - Ipsilateral impairment
        
        motor function, proprioception, sensation (vibration, 2-point discrimination
        
        NORMAL: pain and temperature perception
      - Contralateral impairment
        
        Loss of pain and temperature perception
        
        NORMAL: Motor function
- - - - Why?
        
        Spinal canal loses stability in favor of mobility
      - T12-L1 also commonly injured
  - - - No function maintained from neck down. Need ventilator to breathe
    - - Intact arm function
    - - Control of trunk above umbilicus
    - - Most thigh mm, allows walking with long leg braces
    - - Diaphragm, which allows breathing
    - - Most leg mm, allows walking with short leg braces
    - - Some arm and chest mm
